Duolingo Review (2024)

Duolingo was the first free language-learning app to rival expensive paid programs. It offers plenty of self-paced exercises to help you build a basic understanding of dozens of languages or review one you already know. It's easily the best free language app you can find, and our Editors' Choice winner. Even when measured against paid language-learning programs, the content is so good that Duolingo still ranks among the best software for learning a language and earns a perfect five-star score.

Which Languages Does Duolingo Teach?

For speakers of English (meaning the instruction is in English), Duolingo has courses in 37 languages, excluding languages from works of fiction (Klingon and High Valyrian are offered) and one course still in development (Xhosa). There are many more courses if you add up all those that use a different language of instruction, for example, Catalan for Spanish speakers and French for Arabic speakers.

The 37 real-world languages for English speakers are Arabic, Chinese, Czech, Danish, Dutch, Esperanto, Finnish, French, German, Greek, Haitian Creole, Hawaiian, Hebrew, Hindi, Hungarian, Indonesian, Irish, Italian, Japanese, Korean, Latin, Navajo, Norwegian, Polish, Portuguese (Brazilian), Romanian, Russian, Scottish Gaelic, Spanish, Swahili, Swedish, Turkish, Ukrainian, Vietnamese, Welsh, Yiddish, and Zulu.

If you know someone looking to learn English, Duolingo has ESL programs for speakers of many languages: Arabic, Bengali, Chinese, Czech, Dutch, French, German, Greek, Hindi, Hungarian, Indonesian (Bahasa), Italian, Japanese, Korean, Polish, Portuguese, Punjabi, Romanian, Russian, Spanish, Tagalog, Tamil, Telugu, Thai, Turkish, Ukrainian, and Vietnamese.

While 37 languages is a huge catalog for English speakers to learn, it's not comprehensive. If you need a language that Duolingo doesn't offer, I recommend seeing if Pimsleur offers it first and, if not, Transparent Languages and finally Mango Languages. If you want to learn American Sign Language, which very few apps offer, the best place to go is SignIt ASL.

Is Duolingo Free? How Much Does Super Duolingo Cost?

Duolingo started as a free app with the promise to remain free forever. The company has kept that promise by becoming ad-supported and offering a paid membership, now called Super Duolingo (it used to be called Duolingo Plus). You do not need to pay for Super to use Duolingo. Just sign up for the app with an email address and password, and you're set to go. With a free account, you can study as many languages as you want.

The Super membership costs $7.99 per month, with a discount if you pay for a year upfront ($47.99). There's also a family plan that's good for up to six people, which costs $71.99 per year.Compared with the last time PCMag reviewed Duolingo, the cost of these paid plans has come down.

What does Super Duolingo get you? It removes ads and allows you to use the mobile app to an unlimited degree, whereas free users have to pause the mobile app if they get too many questions wrong in a certain period. Paying members also can practice their mistakes as Duolingo keeps track of them, and they get unlimited special Legendary levels, mastery quizzes, and unlimited Test Outs.

In looking at the prices for other language learning apps, the $47.99 per year price is competitive, and the monthly price is on the low side, too. Yearly access for similar programs typically costs between $100 and $200, with more traditional software (the kind you keep forever) falling into the same range.

Should You Pay for Super Duolingo?

You might consider paying for Super Duolingo if you love Duolingo and want to support the people making it or if you primarily use the mobile app rather than the web app. The web app and mobile app are nearly identical except for one big difference: hearts.

In the Duolingo mobile app, you start with five hearts. Every time you get an exercise wrong, you lose one. When you're out of hearts, you can no longer do exercises until you earn some back. The way you refill hearts is by waiting (five hours per heart) or by spending 350 gems, which you earn by simply using the app. With a Super membership, you don't ever have to worry about hearts. But you also don't have to worry about hearts in the web app because they don't exist there! In other words, you can practice and learn for as long as you want and not pay anything, as long as you log in to Duolingo on the web instead of the mobile app. If you're going to use Duolingo for free, I highly recommend using it on the web to prevent heartache over the hearts system.

Certainly, there are times when it makes sense to use the mobile app because you're on the go and have a few minutes to learn. But if you're a free user, use the web app as much as possible to get the most out of Duolingo.

Getting Started With Duolingo

Since Duolingo launched, I've used it to study or review multiple languages. Some of them were new to me, and some I had learned before. I use it to practice and refresh my Spanish, which I have to speak regularly and have studied in classroom settings. A few years ago, while living in Bucharest, I used Duolingo in the same way for Romanian. I first took a class, then added Duolingo, and finally transitioned to using Duolingo in conjunction with a tutor. If you see Duolingo as a complementary study aid and use it alongside other learning methods, it's the best app you'll find.

When you first get started, and depending on the language, there may be a placement test if you already have some knowledge of the languages. By taking the placement test, you may be able to skip some of the more elementary lessons, such as learning simple words and verb conjugations.

You always have the option to start from the beginning if you want. As mentioned, you can study as many languages as you want at a time, and you can switch between courses at any time.

Duolingo's Structure

Learners often take structure for granted. When it's present, no one notices it. But when it's missing, learning can seem painful and aimless. What exercises should I do next? Am I ready to learn new words? Should I review what I learned yesterday?

Duolingo is highly organized and structured. The app's home screen displays a list of modules in order. Every module has a topic, whether it's grammatical (Reflexives, Imperfect tense) or thematic (Arts, Sports). Each module contains multiple lessons. You have to pass a certain number of lessons to unlock the next set of modules. On average, each lesson takes me three or four minutes to complete.

You mostly work in chronological order, although you can go back to a lesson you've already completed and redo it any time you want. As you progress, words and concepts you learned earlier reappear. New words get highlighted. Once you've finished a fair amount of introductory material, you can review what you've learned by taking a practice test. Look for the dumbbell icon.

Each module has levels. For example, you can pass level one of a module about the preterite to see it marked completed and have it unlock some of the following content. If there are multiple levels for that module, however, you can optionally complete them to continue practicing that skill. If you finish all the levels within a module, the icon for it turns into a gold coin. If you don't return to practice after a long time, the coin icon appears broken. You repair it by returning to the module and completing some levels again.

Some languages don't have as much content as others. Some may have only one level in each module.

I already mentioned that placement tests let you skip modules that you don't need to learn. You also have the option (again, depending on the language and where you are with it) to take a test to exempt yourself from the current module if you find it too easy.Look for an option to Jump Ahead to a new unit.

In my experience, starting from square one isn't a bad way to go. It forces you to review vocabulary and basic concepts, while also giving you time to get acclimated to how Duolingo works. You can also breeze through some of the beginner modules in a few minutes. However, depending on your experience, Duolingo's core exercises might not be challenging enough. In those cases, be sure to explore all the content under Practice, in particular the Stories.

Not all languages have Stories, and most of the rest of the content under Practice is for paying members only—but Stories are included for free. Stories start out easy and advance to an intermediate level—stick with them until all the English disappears.

You can also check to see if there's a Duolingo podcast for your language. The podcasts are designed for intermediate speakers. They use a mix of English and the language you're learning, spoken by native speakers. Duolingo makes the transcripts available online, too. They're not only excellent from a language-learning perspective but also engaging and compelling in their content.

If Duolingo simply isn't challenging enough, another app you can try is Yabla. It's an online service with videos of native speakers using different accents and everyday language. There's much harder content there. And if you need to focus on speaking, try the excellent and fairly priced online classes offered by Lingoda.I recommend those in particular to intermediate and higher level students.

The Duolingo Learning Experience

Duolingo can help you develop a foundation of knowledge for a variety of languages, but it's limited in what it teaches and how much it challenges you. Depending on your goals and prior experience, you'll likely want to strengthen your reading, writing, listening, and speaking skills. You'll also want to know if there's any real language generation, in other words, coming up with an idea that you want to express on the spot without pausing too much to translate from English.

Reading, Writing, Translating

In Duolingo, you're primarily translating, which is a type of reading and writing. Typically, you translate a word, words, or a sentence from the language you're learning into the language of instruction, or vice versa. You might type the answer using the keyboard or cobble together a sentence by selecting the correct words from a word bank. You can choose whether to use the word bank or type out the words, depending on what kind of challenge you want. Sometimes, an exercise has you pick the correct translation from a list of options.

Through these exercises, you learn vocabulary, see verbs in different forms, and generally get used to the structure of sentences in the new language. Translating helps you practice agreement and other grammatical skills, too.

Duolingo could improve by getting you to focus on some concepts more deliberately. For example, when translating a sentence using a word bank, you can usually rule out several words that are completely unrelated to the others. If the sentence seems to be about grandmother's cooking, you can rule out words like architecture and swimming. A harder challenge would be to fill the word bank with similar words or even variations on the same word, such as "hear, hears, heard." Duolingo does have one exercise where you pick the correct form of a word, but it comes up only rarely and it doesn't mix the words with others from the sentence.

Listening and Reading

Listening and reading exercises have improved tenfold since Duolingo launched its series of podcasts. If you speak English, you can listen to podcasts that teach Spanish and French. If you speak Spanish or Portuguese, you can listen to podcasts that teach English. The episodes are phenomenal. You can play them on Duolingo's website or download them to any podcast player app. The benefit of listening via Duolingo's site is that the full transcripts are available there, too.

In each 20- to 25-minute episode, native speakers tell true stories, with a host breaking in regularly to provide context or a summary in English. It's stellar content for intermediate-level speakers or anyone who is not yet at a conversational level.

In addition to the podcasts, Stories also work your listening and comprehension skills a bit more than the core exercises. These interactive stories have you listen to and read a short story while answering questions about what you heard and read. They're only available in select languages, including Spanish, French, German, and Portuguese. The voices used in the story sound natural, which makes them enjoyable. The questions look similar to any other exercise, but to answer them, you must have paid attention to the content of the story and any new words that appeared, so it requires active listening and comprehension. As you advance through this section, the stories get harder and harder, with new vocabulary, more complex sentence structures, and a mix of verb tenses.

Another place you'll find reading is anywhere you see a light bulb icon. One occasionally appears when you click on a new module. These reading sections are in English (or your language of instruction) and typically explain some grammatical point. Sometimes these sections are crucial to your understanding, and in those instances, I wish they were more prominent in the course material. As they are now, they seem secondary.

Speaking and Generating Language

In the core program, speaking and listening aren't given much attention. The speaking exercises are optional. You can enable or disable them in the settings, and you can temporarily disable them if you're in a location where you can't do them.

For these types of exercises, you typically repeat or read aloud something on-screen, and the app assesses whether you've said it correctly. Another way to practice speaking and generating language is through Duolingo's online events, which are meet-ups among people learning the same language as you.

If you need to focus more on speaking and generating, I highly recommend Lingoda's online classes, which I mentioned earlier, and Pimsleur. Pimsleur is an audio-guided program that gets you to think through how you would say a certain phrase or sentence before you open your mouth. Instead of always doing straight translations, you work your way up to responding to prompts.

Duolingo Is the Best Free Language-Learning App

Considering what you can get from it, Duolingo is the best free language-learning app you can find. It's unlikely to take you from a beginner to being fluent, or even conversationally proficient, but it gives you exercises that help you learn a lot about a new language and practice it daily. Using Duolingo is an excellent way to supplement other learning, whether classroom-based or self-taught, making it a five-star Editors' Choice winner for learning languages.

Keep in mind that one app is usually not enough on its own to really push you along your language-learning journey. That's why we recommend pairing Duolingo with classes or another program. If you're a beginner, try Rosetta Stone. If you have a little experience with the language, Lingoda has the best online classes to challenge you. And if you're looking to learn American Sign Language, which most language learning programs don't offer, Sign It ASL is the best.
